The Columbia Model SA-122R miniature force balance accelerometer is a lightweight sensor designed to survive severe mechanical environments without degradation to unit performance. Originally conceived as a replacement for a popular strain gage design frequently used by major aircraft manufacturers, this device has found widespread acceptance by major airframe producers.

The SA-122R eliminates the need for supplementary signal conditioners by providing a standard 0 to 5 volt low impedance output while operating from +28VDC aircraft power. The force balance design delivers accuracy and stability far superior to that which can be expected from a comparably priced strain gage system. Consult the factory for customized versions of these sensors.
